This building is easily found at Elektro power plant. It is beside the smoke stack. There is a ladder that leads to a section of the building protruding from the side.
Take the ladder up to the top and crouch for about 10 seconds. I'm unsure if crouching is the determining factor here but in every instance where it happened to me I was crouching.
After about 10 seconds the screen goes black and you will be informed that you have died. There is no sound of any kind during your death.
